V

Referring to the drawings, one form of the invention is shown as applied to a wheel fellv 10 of the demountable tire rim type having a circumferential flange 11 at one side to form an abutment to properly locate the tire rim upon the telly 10. In the present instance the. tire [rim is formed of two sections 12 and 13 divided eircumfem entially and meeting in assembled condition in an overlapping or ra be ed joint let i which on the tire receiving side. lies in a I plane to one side of the medial plane of the wheel. so that there is no danger of pinching the inner-tube oi the: tire.

For the of rigidly locking the n th a o p y ng r ngs F 1 of Fig. 5'; Fig. 8-

sections 12 and 13 together to clamp the tire shoe in place, each section of the rim is provided with a circumferential concave flange 15 and a plurality of tubular lugs 16 arranged at suitable laces about the rim and on the face which is to seat upon the felly 10. Each of the lugs 16 is provided with a through slot 17 and a laterally projecting key block 18, the arrangement of these being alike in each instance so" that when the device is assembled the slots of the pairs of lugs 16 will register and'the key; blocks 18 lie in the same plane The set of tubular lugs upon the rim section 13 are provided respectively on their outer ends w h s p 2 so t at h e h re ns locking part will be limited in its motion and properly positioned for locking purposes. This cooperating locking part consists in the present instance of a keeper bar 21 of circular section in; order to have a snug slid ing fit inthe tubular members 16 and carries a o n me ally p je t g ke per 2 which has a neck portion 23 to fit freely within the slot 17 of the lug 16 so that the keeperbar can be passed through a pair of lugs16 until the keeper 22 is beyond the end off-the luglfi when the bar 21 can be turned to bring the keeper 22 over theend of the lug to prevent withdrawal of the keeper bar-21. As here shown, the rim section 13 has a cutway portion 24 to permit free rotation of the keeper in the desired manner. Spaced from the keeper 22 a distance substantially equal to the end to end length of two abutting lugs 16 thekeeper bar 21 is providedwith a head 25 of in creased diameter sothat in assembled condition the keeper bar 21 rigidly clamps the twolugs 16 together and thereby rigidly fastens the two tire sections together at the required number of points about their eircurnference. i a

In order to lock the keeper bar to hold he w m sec i s e emb th ead 25 is Pro d th a fl n e 26 i h; 11m: i e th a R t 2 arr n d o re i sh w 28 hieh n h pre i st nce i m un e 1 1 9 l i el s i p n 30 tt ch d to he diaeen m aetitia y the ir as e fit ed new t e two rim sections 12 and 18 the keeper bars 21 are respectively entered in the tubular lugs 16 and when the respective keepers leave the slot 17 the keeper bars 21 are turned to the locking position out ot register with the slot and the spring pawls 28 at that time respectively. snap into the notches 27, thus looking the sections of the rim together and clamping the tire fast to the rim.

For the purpose ot mounting the assembled tire and tire rim upon the wheel telly the latter is provided with plurality of grooves 31 extending transversely across the rim receiving surtace and having a portion 32 circular in contour to conform to the curvature ot the lugs 16 and an offset portion 33 contorming to the contour ot the keeper block 18. In the assembled condition of the tire rim the keeper bar 21 has its keeper 22in alinement with the block 18 and consequently the tire rim can he slipped directly over the telly and the keeper bars 21 pass respectively into the grooves 31 in order to bring the keepers 22 to a position projecting from the opposite side of the telly. In this position the keeper bar 21 of each locking device is given a partial turn so that the keepers 22 are out of register with the block slot 33 and consequently the parts are rigidly clamped together because the flange 26 of each of these bars is then abutting the opposite side of the telly 10. This flange 26 is provided with a second notch 34 also arranged to receive the spring pressed locking pawl 28 and in its locking position receives the pawl and holds the keeper rigidly in its locking position.

' As an auxiliary means for interlocking the keeper bar 21 and telly, the'tormer is provided with a projecting detent 35 which is arranged to seat in a locking slot 36 ot the telly, there being one ot these slots tor each of the'transverse grooves 31, and the slots open respectively into such grooves so the the turning of the keeper bars 21 brings the respective detents into the slots 36. The keeper bars 21 terminate respectively at the end opposite to the keepers 22 in a polygonal shaped extension 37 to receive a wrench or other suitable tool. for turning the keepers in' the required manner. Y

From the foregoing it will be apparent that a demountable rim fastening means has been devised wherein nuts and bolts have been dispensed with as well as clamping lugs requiring removal by special wrenches betore the tire rim can be taken oil. Further- ,more the present construction provides a simple, expeditious means tor releasing a tire trom a rim so that instead 0t unlocking the meeting ends of a split rim and laboriously prying the tire trom its rim, all that is necessary is to release the keeper bars by a partial turn thereof and withdraw them from the rim grooves. l/Vhen this is done the circumterentially divided rim allows the tire to be taken off without ettort.

The simplicity ot the construction is evident by the minimum number of parts; by the absence ot parts requiring tools to assemble and disassemble the tire, tire rim and telly; and by the provisionot a common means for clamping the tire to the rim, and tastening the tire to the telly.

Having thus described my invention, I claim:

1. A 'wheel rim constructioncomprising a telly provided with. a plurality of transverse slots in the taco thereot, a rim having a plurality ot tubular lugs arranged respectively to seat in said slots and having a slot lengthwise thereof, keeper bars arranged to rotatably fit within said lugs, keepers on the respective bars to pass through said lug slots and be turned out ot register therewith to lock said parts together, and locks for respectively retaining said keepers in locked position.

2. A wheel rim construction comprising a plurality ofkeeper bars provided with radially projecting keepers, a demountable circumterentially' split tire rim having lugs provided with slots to receive and seat the respective keeper bars, a telly having transverse grooves to seat said lugsrespectively, said bars in assembled condition projecting said keepers to one side of said telly for turning movement out of register with said grooves and slots, and means to lock each bar in its out, of register position whereby said tire, said rim and said telly are interlocked.

3. In a wheel rim construction, a circum-f terentially divided tire rim, radial lugs on each rim section, said lugs having bores arranged tor mutual registry in aligned pairs, a bar insertable through said bores tor rotation in said lugs, means on said bar for locking said rim sections together on rotation of said bar, said means being formed tor locking engagement with opposite sides ot a wheel telly on further rotation of said bar.

4. In a wheel rim construction, the combination with a telly having a transverse peripheral groove opening at each side thereof, of a tire rim circumterentially divided in two sections, guide lugs 011 each section tor seating engagement in said groove and apertured transversely in alignment, a bar insertable through said lug apertures for rotation in said lugs, means on said bar tor clamping saidrim sections together on r9- tation of said bar through a predetermined degree, said means being formed tor engagement over the opposite sides of said telly at the ends of said groove on turther rotation of said'b'ar to locksaid rim to the telly.

5. A'wheel rim construction comprising a in service position and locking said rim to 10 the felly successively by rotation of the keeper, and means for retaining said keeper in both its rim section clamping and rim locking positions.
